I dont see how this is a big loss for Valencia.
Aimar has only had 1 great year at The Mestalla where he has really shown - that was in '03. Incidentally, that wasnt a very good year for Valencia in the League or the CL. He has never put together a string of consistent performances as far as i can remember (Valencia fans, feel free to correct me if i am mistaken) and is the kind of player that is too hot and cold so to speak - fades in and out of games too much. I reckon a player should be judged on PERFORMANCE first and foremost, instead of being overrated entirely on reputation. He had great days with River Plate and has more potential and talent than the whole Valencia team put together, but he has hardly been anywhere near as influential to his team's success as his team mates Baraja, Albelda, Ayala, and Vicente. Last season, Valencia did superbly without him featuring regularly (he played only 20 odd games, a lot of substitutions - once again, correct me if am wrong) so they obviously can live without him.
Could Valencia ever manage to be a strong, competitive side without figures like Baraja, Albelda or Vicente? I doubt they would - if someone could mention an occasion when either of these 3 players have been injured and post how good/poor Valencia were in their absence that would put everything into perspective. We know that they could do without having Aimar as a permanent fixture.
This is simply my opinion, feel free to argue or correct me if I have missed anything.
the above has been quoted by spirit - of - srt in other thread where he was doubting Aimar's conibution to valencia , i think this match showed you a little bit of Aimar' performance and his contribution to his team, it is not always the player who scores goals is the key figure but it is always the player who keeps his team play to the best level which is very important , the player which gets his teammates out of difficult situations and assisting them,he is one of the best playmakers in the world along with the genuis requilme ( with zidane level is not the same of 2 years ago i think these 2 players are the best in this position and this will be proved during this summer confedration cup and next year world cup )
